Title: Probe test for cyanide in sewage - uses semipermeable membrane to collect ions for indicator reaction
IPC: G01N33/18
Filed: 1979-09-28
Abstract: The probe detects the presence of a cyanide in sewage by collecting the ions thorugh a semi-permeable cellulose membrane. This forms a tube contained in a probe which is placed in the sewage. Air contg. chloramine T is passed through the probe. The chloramine reacts with cyanide ions and removes them for analysis. The product is tested by reacting it with barbituric acid in pyridine and hydrochloric acid. The product turns red if cyano-chloride is present. This method can test for other substances by the use of different reagents.

Title: Mortise and tenon joint for modular furniture - has self locking mechanism, comprises logs on tenon fitting into slots in mortise and locking when components are rotated w.r.t. one another
IPC: F16L37/252
Filed: 1980-01-15
Abstract: The joint consists of a mortise (3) which has two inclined grooves (6,6'). The tenon (2) of the male element (1) has two corresponding projections (5,5'). During assembly these two projections pass axially along the groove (7,7') and enter the circumferential grooves at their lowest points. By turning the two elements relative to each other a tightening and locking of the joint is achieved. The device is mainly applicable to modular furniture where intermediate items such as shelves may be clamped between the two halves of the joint. Another application is in the joining of tubes for fluids. Here a gasket (8) and a 'O' ring would ensure a watertight joint.

Title: Vehicle tyre pressure sensor for remote monitoring - uses safety valve coupled to sensor connected to induction circuit fed by modulated AC
IPC: G01L9/00
Filed: 1980-05-09
Abstract: The pressure in a tyre is detected by a safety valve which closes when a rapid fall in pressure occurs. The pressure measurement is transmitted via a tube to a sensor at the hub cover against the wheel rotational shaft. The sensor is coupled to the secondary winding which is open or closed circuited by the sensor to indicate pressure relative to a threshold value. The winding is inductively coupled to a primary winding whose current from a modulated or AC supply is measured by a galvanometer to indicate whether or not the secondary is an open or closed circuit.

Patent FR-2493553-A1 (FR)
Inventor: GEESEN MICHEL
IPC: G04F10/10
Filed: 1980-10-31
Abstract: The apparatus gives an indication of the location in time between two successive clock signals of an event to be timed. Such an event may be the arrival of a laser pulse at a satellite. An integrator circuit (C84) is charged by a relatively high charging current from a first current generator (66) during the period of time between the event and the next clock signal. The integrator circuit is then discharged by a smaller current of opposite sign from a second current generator (80). The ratio of the charge and discharge currents "stretches" the inter clock pulse time interval to a length that can be measured by counting clock pulses as the integrator discharges. For this factor to be useful, it is essential that the charging current remains constant during charging and from one charging occasion to the next. This is achieved by keeping the generator (66) generating current constantly and by diverting the current through an integrator circuit by-pass (R78) when not integrating. Switching is done using two transistors (Q71 and Q72) that are as identical as possible, and independently controlled in phase opposition. The by-pass current is detected and used to regulate the generator (66). Provided both transistors deviate in the same manner from nominal characteristics, this provides accurate compensation for variations in the other transistor also.

Title: Glass door for refrigerated display case - has air conduit extending around case forming air curtain across door opening during refrigeration cycle
Inventor: ABRAHAM FAYEZ FARES
IPC: F25D21/12
Filed: 1980-11-10
Abstract: A refrigerated display case has a display section within a cabinet and movable door covering the access opening to the display section. An air conduit extends along the top, bottom and rear walls of the cabinet. The air conduit has an outlet opening and an inlet opening and air leaving the outlet opening will be directed towards and received by the inlet opening forming an air curtain across the front opening of the cabinet along the path inside the door. During a refrigeration cycle of operation of the display case, refrigerated air is circulated through the air conduit and a refrigeration mechanism arranged within the conduit by a positive pressure air flow. This establishes a refrigerated air band and a refrigerated air curtain across the front opening in the cabinet. During a defrost cycle of operation, the refrigeration mechanism is turned off and the door covering the front access opening is slightly opened. Ambient air is then drawn into the air conduit and circulated through the conduit.

Title: Blow moulded moulds for cast concrete structures - to produce a smooth surface or a protective cover
IPC: B28B7/34
Filed: 1980-11-28
Abstract: Moulds for making cast concrete mouldings for e.g. balustrades etc. are produced in one piece by blow moulding. The moulds may be torn or split and removed to expose the castings or may be retained as an integral protective cover during transport or subsequent use. Pref. the moulds are produced from polypropylene by an injection-blowing process. Casting of the concrete is vibration-assisted for greater densification and to produce migration of the finer filler particles to produce a smooth surface. Use of one piece moulds avoids appearance of mould parting lines or the surface of the castings, if used exposed. The amt. of cement required can be reduced, with up to 50% being replaced by aggregate, compared with conventional cast mouldings.
